People who eat junk food are exposed to dangerous levels of phthalates

Eating junk food could not only be making you fat, it could be affecting your hormones as well. This was the stomach-turning conclusion made by researchers from George Washington University who found that people who ate more junk food or frequented fast food restaurants had a significantly higher chance of being exposed to phthalates, a class of endocrine-disrupting chemicals. The study, published in Environment International, suggests that fast food and cafeteria meals contained 35 percent more phthalates than food cooked at home.

As explained by senior author Ami Zota, ScD, MS, and assistant professor of environmental and occupational health at Milken Institute School of Public Health (Milken Institute SPH) at the University, “Our findings suggest that dining out may be an important, and previously under-recognized source of exposure to phthalates for the U.S. population.”

Researchers used data from the National Health and Nutrition Examination Survey (NHANES) collected between 2005 and 2014. They analyzed the nutritional information provided by 10,253 participants within 24 hours and cross-checked that with each person’s urine sample. They found that 61 percent of the participants had eaten out on the previous day. Disturbingly, of this population, the authors noted that:

Adolescents who ate fast food or food outside of the home had 55 percent higher levels of phthalates compared to those who ate their food at home.

Certain foods, such as cheeseburgers and other sandwiches, had extremely high levels of phthalates, but only if they were purchased at a fast food outlet.

Overall, the team concluded that people who ate the most fast food, burgers, and fries, had phthalate levels 40 percent higher than those who ate at home or prepared their own food.

It is interesting to note that phthalate exposure increases when dining out, regardless of the type of restaurant you choose to go to. These levels do fluctuate, with fast food outlets being the most dangerous, but it does highlight the importance of eating at home and with food that you yourself have made.

Phthalates and you

Phthalates are a group of chemicals used to increase the flexibility of plastic and vinyl. They are a popularly used in the production of cosmetics, personal care products, shower curtains, detergents, adhesives, and a lot more. Data reveal that exposure to these chemicals can cause several adverse side effects, not least of which is damage to the reproductive system.
